The movable part has the shape of a frame 14 with grooves on the inner surface. When the shaft 1 rotates, the rollers 18, under the action of K 7, move the punch 9 upwards and, together with the workpiece, inserts it into the cavity M 8. K 5 lowers the ejector 10. The ring 12 is distributed and the wall sections are stamped. Then, under the action of K 6, frame 14 moves along radius D 2. Its grooves are aligned with cavities M 8.

Description

The invention relates to equipment for metal forming and can be used in various fields of engineering.

The purpose of the invention is the expansion of technological capabilities by processing sections of the walls of hollow products, in particular, relief molding and perforation of walls.

FIG. 1 shows a device, a longitudinal section; in fig. 2 shows section A-A in FIG. one; in fig. 3 - tool block at the time of punching and at the time of ejection of the finished product; in fig. 4 - finished product.

The working rotor contains a shaft I, a drum rigidly fixed on it, consisting of disks 2-4, copiers 5-7 fixedly mounted on a frame (not shown). In the drum, instrumental blocks are evenly distributed along the circumference. Each tool block includes a matrix 8, a punch 9 and an ejector 10. The punch 9 is installed in the punch holder 11 disposed in the disk 4 with the possibility of movement in a direction parallel to the axis of the drum. On the surface of the punch 9 there is a ring 12 made of elastic Mj3Terial. The matrix 8 is made up of a component part 13 fixed on the disk 3 and the part having the shape of frame 14 connected to part 13 by springs 15 carrying roller 16. The working surface of the frame has grooves 17. Roller 16 during operation of the working rotor in contact with the copier 6. The punch holder 11 carries the roller 18 and through this roller interacts with the copier 7. The pusher 10 carries the role-to-19 and through this roller interacts with the copier 5.

The device works as follows. The shaft 1, receiving rotation from the drive, rotates the drum rigidly fixed on it, consisting of disks 2-4, in the direction indicated by the arrow (Fig. 2). In this case, the rollers 18 and 19, as shown by the fixed copiers 5 and 7, report a reciprocating movement of the ejector 10 and the punch holders 11 together with the punch 9.

Workpieces, pre-oriented by a transport device (not shown), are fed into the zone of action of the punch 9 and as a result of the latter moving upward onto it are put on and then introduced into the working cavity of the matrix 8. With further rotation of the system, the matrix — punch — ejector around the vertical axis the device, the fixed part 13 of the matrix 8 is locked from above by the ejector 10, and the elastic ring 12 of the punch 9 under the action of the upward-moving punch holder 11 is distributed in the transverse

direction, presses the workpiece to the machines of the fixed part 13 of the matrix 8, and when the required specific pressure occurs in it, it sequentially performs the operations of punching and forming protrusions in the walls of the workpiece.

Then, in the process of further rotation of the system around the axis of the shaft 1, the roller 16 runs over the stationary copier 6 and, compressing the spring 15, moves the frame 14 to align its grooves 17 with cavities in the case of the fixed part 13 of the matrix 8 to form protrusions on the surface of the workpiece, and the ejector 10, moving together with the punch 9 downwards, removes the workpiece from the working cavity of the matrix 8. The workpiece, falling into the gripping bodies of the transport device, is carried out last from the working rotor's zone of action. The roller 6 comes off the copier 7 and the frame 14 under the action of the springs 15 returns to its original position and the whole process repeats again with further rotation of the drum around

shaft axis 1.

The described embodiment of the working rotor allows the relief forming of the wall sections of hollow products and punching holes in them and thereby expands the technological possibilities of using working rotors.
